Channel struct

Implementations

impl<'a, S: TimerSpeed> Channel<'a, S>

pub fn new(number: Number, output_pin: impl PeripheralOutput<'a>) -> Self

Returns a new channel.

Trait Implementations

impl<S> ChannelHW for Channel<'_, S>

where S: TimerSpeed,

Available on crate feature unstable only.

fn configure_hw(&mut self) -> Result<(), Error>

Configures Channel HW.

fn set_duty_hw(&self, duty: u32)

Sets duty in channel HW.

fn start_duty_fade_hw( &self, start_duty: u32, duty_inc: bool, duty_steps: u16, cycles_per_step: u16, duty_per_cycle: u16, )

Starts a duty-cycle fade HW.

fn configure_hw_with_drive_mode(&mut self, cfg: DriveMode) -> Result<(), Error>

Configures the hardware for the channel with a specific pin configuration.

fn is_duty_fade_running_hw(&self) -> bool

Returns whether a duty-cycle fade is running HW.

impl<'a, S: TimerSpeed> ChannelIFace<'a, S> for Channel<'a, S>

where Channel<'a, S>: ChannelHW,

Available on crate feature unstable only.

fn configure(&mut self, config: Config<'a, S>) -> Result<(), Error>

Configures channel.

fn set_duty(&self, duty_pct: u8) -> Result<(), Error>

Sets duty % of channel.

fn start_duty_fade( &self, start_duty_pct: u8, end_duty_pct: u8, duration_ms: u16, ) -> Result<(), Error>

Starts a duty fade from one % to another.

There is a constraint on the combination of timer frequency, timer PWM duty resolution (the bit count), the fade “range” (abs(start-end)), and the duration:

frequency * duration / ((1<<bit_count) * abs(start-end)) < 1024

Small percentage changes, long durations, coarse PWM resolutions (that is, low bit counts), and high timer frequencies will all be more likely to fail this requirement. If it does fail, returns an error.

fn is_duty_fade_running(&self) -> bool

Returns whether a duty-cycle fade is running.

impl<S: TimerSpeed> ErrorType for Channel<'_, S>

Available on crate feature unstable only.

type Error = Error

Error type

impl<'a, S: TimerSpeed> SetDutyCycle for Channel<'a, S>

where Channel<'a, S>: ChannelHW,

Available on crate feature unstable only.

fn max_duty_cycle(&self) -> u16

Get the maximum duty cycle value.

fn set_duty_cycle(&mut self, duty: u16) -> Result<(), Self::Error>

Set the duty cycle to duty / max_duty.

fn set_duty_cycle_fully_off(&mut self) -> Result<(), Self::Error>

Set the duty cycle to 0%, or always inactive.

fn set_duty_cycle_fully_on(&mut self) -> Result<(), Self::Error>

Set the duty cycle to 100%, or always active.

fn set_duty_cycle_fraction( &mut self, num: u16, denom: u16, ) -> Result<(), Self::Error>

Set the duty cycle to num / denom.

fn set_duty_cycle_percent(&mut self, percent: u8) -> Result<(), Self::Error>

Set the duty cycle to percent / 100
